' vz ciaimsicifzsif-zsi an opening I9 formed in the top wall of the casing I 0,'so that the air drawn in throughthe inlet Il by the blower I6,is blown thereby through'the opening I9 into thecooling and'washing' chainber II, from which it is. directed out through-.the outlet 22to distribution pipes or directly to the room area, as desired. l.

,The motor 2liv hich operates .the blower JIS also operates, through a Vclutch 23 and aV sys` tem of gears 24, a dual piston pump, generally indicated at L21. yThis pumpyis mounted in a housing 25 arranged in the casing Ill. When the. motor -20 and' blower I6 `are' inA operation the pumpr21 sucks water uprfrom the tank sectionV I2 of the casing I0 by way of the pipe 26ffrom which the waterfiows into the pump 21, thence out of the pump by wayof pipe 28 to ,an overflow` housing'V or reservoir29; from the housing 29 through a pipe30 into a distributer passage 3I formedin the ring 2l (Fig. 8) and fromthedistributer passage 3l through'a seriesof branch passages or nozzles-32,` formed in the ring 2i, and which direct the water into the `blower VIii to be commingled thereby with the ,airsucked into the blowervthroughthe inlet I8. l ,K f

Apipe 33 `leads from the upper chambered portion of the overow housing valve 29 into the distributer passage 3i. If the pump 21 is [sup-` plying water to the line 28-30 faster than thc same c'an be injected into the blowerl through 30 the branch passagesor noazles` 32, the water will rise into the upper chambered portion of the overflow housing 29, and should the housing 29 ll up to the level ofthe pipe 33 it will. then overflow through pipe '33 into `the distributer passage 3l. The upper chambered portieriA is provided with. an open top that is closed by a pivoted cap, asbest shown in Fig. 9, so thatif the ilow should become too great to prevent aV uniform ow through the nozzles 32, it will force the cap open and relieve the pressure, with Vthe result it will be seen that the overflow housing also acts in the capacity of a relief valve.

'Ihe pump 21 is operated from the motor 20 by a conventional clutch and gear mechanism 23--2l,`which is constructed as follows: On one end of the motor shaft /34 is aworm 35 (Figs. 6 and 9) which meshes with a gear`36 that is fast on a vertical shaft 31. On the shaft 31 is a worm 38 (Figs. 9 and 10) which meshes with a 50 gear 33 which is fast on a horizontal shaft Ml.,` Formed on this gear 39 is a'clutch face l I. Fast on the shaft 40 is a clutch face 42 and iloating 'on the shaft Il between the clutch faces 4I and 42 is a gear body having gears and 44 of dif- This invention relates to certain novel improvements'in 'air cooling and Washing devices, and'l has for itsk principal object the provision 'offan improved construction of 'this character which manufacture. Y A

An object of this inventionv is to provide a new, compact, portable, relatively simpleand inexpensive air cooling and washing device.

" Other objects will appear hereinafter.

The invention consists in-the-novel combination and arrangement of parts to be hereinafter describedand claimed.

The invention will be best understood by referencev to the accompanying drawings, showing the preferred form of construction, andnin which: '1 Fig.A 1 is a top plan view `of thefinvention Fig.` 2 is a vertical sectional view on line 2-2 in'Fis. 3:4 A f Fig. 3 is a side elevational view, online 3-3 in Fig. 2, with a part ofthewall of the air washing chamber broken away to show thecooling unit therein;v g Y' A Fig. 4 is a view on line 4-4 in Fig. 2, partly in bottom plan and partly in section;

Fig. 7 'is a sectional view on line 1-1 in Fig.v6;

Fig. 8,lis a sectional view on line 8 8 in Fig. 6;

Fig. s a sectional view on Aline 9--3v in Figr; and f Fig. l0 is a sectional view on line III-I0 in Fig. 9.' l 1 In the drawings I0 indicates generally a casing, the interior 'of which provides an air cooling and washing chamber II. This casing III includes a lower section I2 which provides a water tank and an upper section I3 mounted thereon. Arranged in the air washing and cooling chamber II is a gas or vapor expansion coil Il, the ends I5 of which are led outside the casing (Figs. 3 and 5) for connection to a suitable refrigerating unit.

Mounted on the top wall of the casing II) is a blower IG over which is arranged a housing I1. The blower I6 is operated by an electric motor 2l, also mounted onthe top of casing I0. The housing I1 has an inlet I! which is provided by a ring 2| attached thereto (Fig. 6), and through this inlet I 8 air is sucked, in the use of the device, into the blower II. The bottom of the housing I1 communicates with the chamber I I through the motor.

ferent diameters formed thereon :said gear body havinga clutch face formed in each end thereof.

Arranged parallel to the shaft 40 is a crank shaft 45 on which are fast gears 46 and 41. Attached to the crank shaft 45 at its ends are throws 49 that are spacedfrom each other relative to the circumference of the crank shaft 45. Operatively connected to the throws 49 are connecting rods 50 that are attached at their lower ends to iiexible diaphragm pistons 5I. 'I'hese pistons Vwork alternately in the cylinders 52 of the pump 21, by reason of the spacing of the throws 49. The cylinders 52 are interconnected by a pipe 53 which leads into the.pipe 28, (Fig.4).

The water supply pipe Y26 opens by way of a branch passage 54 (Fig. 9) into the bottomrof.

each of the two pump cylinders 52, and in each branch passage 54 is a ball check valve'55. EachV of the cylinders 52 communicates with the T 53 by way of a passage 56 (Fig. 6), and in each of these passages 56 is' aV ball check valve 51.

The yspeed of the'pump 21 maybe varied by' shifting the pivotal clutch shift lever `4Il (Figs. 9 and 10) so as to mesh the gear 43 `Vwith the gear 46, or to mesh-the gear 44 with the gear 41. Y

Thespeed ofthe motor 20 and blower I6 may be varied by means of a suitable variable. resistance or rheostat 58 arrangedV in circuit with Operation: The motor 20 is set in operation and the same drives, directly, the blower I6 (Fig. 6). At the same time the motor 20 operates the pump pistons 5I through the clutchy and gear systems 23 and 24, which are of conventional design, as hereinbefore stated and described (Figs. 6, 9 and 10). The pump pistons 5I are alternately reciprocated up and down, and on the suction or up stroke of each piston 5I sucks water into the corresponding cylinder 52, from the tank I2 of casing I0, by way ofthe water supply line 26-54 and the corresponding ball check valve 55. On the downstroke of eachk piston-diaphragm 5I, thercorresponding ball check valve 55 reseats and closes by gravity and the downwardly moving piston forces the water out of the cylinder 52 through the corresponding passage 56 and ball check valve 51 into the T 33; thence through the pipe 28, through overflow valve` 29, through the pipe 30 into the distributor passage 3I and from the passage3l through the branch passages or nozzles 32 into the blower I6, to be commingled thereby with the air sucked into the blower through the inlet I8. The blower I6 blows the commingled air and water vapor into and circulates it through the chamber I I, wherein it circulates around the expansion or cooling coil I4, and finally the action of the blower I6 'forces the cooled and washed air out of the chamber II,

by way of the outlet 22, to the room area or to distribution pipes, as desired.

While I have illustrated and described the preferred form of construction for carrying my in- Vvention into effect, this -is capable of variation and modification, without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variationsand modications as come within the scope of the appended claims. l

Having thus describedvmy invention what I claim as new and desire to protect .by Letters Patent is:
